The Psychometric Properties of the Hypersexual Behavior Inventory Using a Large-Scale Nonclinical Sample
The conceptualization of hypersexuality has begun to converge as a result of proposed diagnostic criteria. However, its measurement is still diverse. The Hypersexual Behavior Inventory (HBI) is one of the most appropriate scales used to assess hypersexuality, but further examination is needed to test its psychometric properties among different clinical and nonclinical groups, including samples outside of the United States. The aim of the present study was to investigate the reliability and the generalizability of HBI and to determine a cutoff score on a large, diverse, online, nonclinical sample (N = 18,034 participants; females = 6132; 34.0%; M-age = 33.6 years, SDage = 11.1). Confirmatory factor analysis (CFA) and reliability indices provided support for the structure of the HBI and demonstrated excellent reliability. Employing latent profile analysis (LPA), seven classes emerged, but they could not be reliably distinguished by objective sexuality-related characteristics. Moreover, it was not possible to determine an adequate cutoff score, most likely due to the low prevalence rate of hypersexuality in the population. HBI can be reliably used to measure the extent of hypersexual urges, fantasies, and behavior; however, objective indicators and a clinical interview are essential to claim that a given individual may exhibit features of problematic sexual behavior
Hybrid designs and kick-off production experience for the CMS Phase-2 Upgrade
The CMS Tracker Phase-2 Upgrade requires the production of new sensor modules to cope with the requirements of the HL-LHC. The two main building blocks of the Outer Tracker are the Strip-Strip and Pixel-Strip modules. All-together 47'520 hybrid circuits will be produced to construct 8'000 Strip-Strip and 5'880 Pixel-Strip modules. The circuit designs for the mass production were fine-tuned and kick-off batches were manufactured to verify the latest changes in the designs before the series production. This contribution will focus on lessons learned from the prototyping stage, design optimization details for the mass production as well as test results and production yield from the kick-off batches
TWEPP 2021 Topical Workshop on Electronics for Particle Physics
Sixteen thousand 2S front-end hybrids and twelve thousand PS front-end hybrids will be produced for the CMS Tracker Phase-2 Upgrade. The hybrids consist of flip-chips, passives and mechanical components mounted on a flexible substrate, laminated onto carbon-fibre stiffeners with thermal expansion compensators. In the prototyping phase, several critical issues have been solved to manufacture these complex circuits. Final designs are now reaching readiness for the full-scale production. High-density circuit design practices, lessons learned during the prototyping phase and different improvements for manufacturability will be presented in this contribution
Front-end hybrids for the strip-strip modules of the CMS Outer Tracker Upgrade
The CMS Outer Tracker planned for the HL-LHC Upgrade contains strip-strip and pixel-strip silicon modules. Each of them includes two high-density front-end hybrid circuits, equipped with flip-chip ASICs, passives, connectors and mechanical structures. Several strip-strip hybrid prototypes have been produced using the CBC2 front-end ASIC. Feedback from these developments helped improving the hybrid's testability and the production yield. The availability of the concentrator ASIC's footprint and of the new CBC3 front-end ASIC enables the design of all strip-strip hybrid variants. In this work, the development milestones and the final designs are presented together with chosen solutions
Manufacturing experience and test results of the PS prototype flexible hybrid circuit for the CMS Tracker Upgrade
The CMS Tracker Phase-2 Upgrade for HL-LHC requires High Density Interconnect (HDI) flexible hybrid circuits to build modules with low mass and high granularity. The hybrids are carbon fibre reinforced flexible circuits with flip-chips and passives. Three different manufacturers produced prototype hybrids for the Pixel-Strip type modules. The first part of the presentation will focus on the design challenges of this state of the art circuit. Afterwards, the difficulties and experience related to the circuit manufacturing and assembly are presented. The description of quality inspection methods with comprehensive test results will lead to the conclusion
Testing of the Front-End Hybrid Circuits for the CMS Tracker Upgrade
The upgrade of the CMS tracker for the HL-LHC requires the design of new double-sensor, silicon detector modules, which implement Level 1 trigger functionality in the increased luminosity environment. These new modules will contain two different, high density front-end hybrid circuits, equipped with flip-chip ASICs, auxiliary electronic components and mechanical structures. The hybrids require qualification tests before they are assembled into modules. Test methods are proposed together with the corresponding test hardware and software. They include functional tests and signal injection in a cold environment to find possible failure modes of the hybrids under real operating conditions
Reliability test results of the interconnect structures of the front-end hybrids for the CMS Phase-2 Tracker Upgrade
High Density Interconnect (HDI) hybrids are being developed for the CMS Tracker Phase Two Upgrade for the HL-LHC. These hybrids are carbon fibre reinforced flexible circuits with flip-chips, passives and connectors. Their operational lifetime is determined by the reliability of the solder joints of the surface mount components (flip-chips, passives, connectors) and the copper traces and vias in the hybrid substrate. Specific test coupons were exposed to accelerated thermal stress cycles, aiming to test the reliability of the solder joints, vias and traces. Results from different suppliers and technologies will be evaluated and compared
CMS Outer Tracker Phase-2 Upgrade on-module powering
The CMS Tracker Phase 2 Upgrade for the High Luminosity Large Hadron Collider will use two module types, which contain different sensor configurations and custom ASICs. Guaranteeing the power integrity of all modules for the full lifetime of the detector is crucial for the detector performance. This article describes the historical evolution of the powering architecture, the problems encountered, and the solutions implemented for the two types of modules, as well as the final on-module powering strategy along with the data and modelling that motivated it
Development of an Optical Readout Hybrid for the CMS Outer Tracker Upgrade
The pixel-strip modules for the CMS Tracker Phase-2 Upgrade for the HL-LHC integrate a readout hybrid (PS-ROH) for the control and data acquisition link. This hybrid is based on the new, low power and compact gigabit transceiver (LpGBT) and the versatile transceiver VTRx+ specifically designed for the upgrade. A characterization board was first designed to qualify the design rules and the achievable timing performance of the gigabit block. This design enabled the development of the PS-ROH for the CMS Tracker PS modules. A testing setup was also developed to verify the PS-ROH performance before its integration into the PS modules
